Provide the utility model embodiment below in conjunction with accompanying drawing:
This automobile headlamp intelligence light variable controller is formed by receiving light unit (I) and control unit (II).Referring to Fig. 1, Fig. 2, wherein light receiving unit (I) comprises receipts light box (1), light receiving unit body skin (2), baffle (3), filter glass (4), light receiving unit circuit board (5), support (6), signal cable (7), indicator lamp (8), photosensitive crystal (9); Receiving light box (1) is installed in the receipts light cell enclosure bodies (2), three holes are opened at its rear portion, the photistor that is used for being electrically connected with wiring board is inlayed, light receiving unit circuit board (5) is inlaid in the bottom of receiving light box (1), and the signal cable of drawing on the plate (7) is delivered to control unit to electric signal.
Control unit (II) comprises control unit shell (10), control unit circuit board (11), automobile headlamp current supply circuit line (12), control unit circuit board (11) is contained in the shell (10), draws headlight current supply circuit line (12) on the slave plate.
Circuit theory is described as follows:
Referring to Fig. 3, optical receiver circuit is made up of three 3DU12 photistoies, three switching transistor 3DK4, three 30K resistors, three the miniature potential devices of 3K, a slice 74HC14 integrated circuit, three 3.3K resistors, three light-emitting diodes, three 33P conies.In the circuit with three photistor 3DU12 as light sensing element, wherein QG1 is used for 150 meters～200 meters of the distance of reaction light intensity of dazzle light at a distance, QG2 is used to respond to 150 meters light intensity with interior automobile dipped headlight.Regulate RW1, RW2, RW3, under the light intensity irradiation of corresponding automotive lamp distance light, dipped beam, high light, make Q1, Q2, Q3 respectively in the conducting of own operation point, emitter potential reaches the logic high thresholding of CMOS gate circuit, and these three logical signals are respectively distance light signal, dipped beam signal, high light signal.Through the output of reverser 74HC14 gate circuit, these three signals are delivered to control unit (II) by signal cable (8).
Referring to Fig. 2, control unit (II) is made up of one-chip computer U5, photoelectric coupling circuit U1, photoelectric coupling circuit U2, photoelectric coupling circuit U3, photoelectric coupling circuit U4, electromagnetic relay J1, diode D1, diode D2, diode D3, diode D4, diode D8, crystal oscillator X, constant voltage power suspply M1 and resistance, electric capacity etc.Wherein U5 can adopt various model micro controller systems, as 8751,8749, Z8,8098,80552 etc.By three electric signal YG, JG of light receiving unit (II) output, QG guides to the P1 mouth of one-chip computer 8751 by signal cable (7) P13, P14, P15 pin, incoming signal as U5, former automobile headlamp manually becomes photosignal and steering indicating light electric signal and is coupled to P10, P11, the P12 pin of the P1 mouth of U5 through diode by photoelectric coupling circuit U1, U2, U3, as incoming signal.The P17 pin of P1 mouth is drawn out to photoelectric coupling circuit U4 as mouth, by isolation drive relay J 1 action of U4.When P17 is low level, photoelectric coupling circuit U4 conducting, relay J 1 action adhesive, headlight current supply circuit and passing light are connected, and make automobile dipped headlight bright; When P17 was high level, photoelectric coupling U4 ended, and relay J 1 discharges, and headlight current supply circuit and country beam are connected, and make dazzle light bright, realize becoming light with this.Under the driving of the program that one-chip computer 8751 solidifies within it, by the incoming signal of P1 mouth being analyzed and being judged, the output of decision P17 pin is high level or low level, make photoelectric coupling circuit U4 conducting or end, to drive relay adhesive or release, make passing light bright or country beam is bright, automatic beam change when reaching meeting, automatically glisten when overtaking other vehicles, and force the realization of distance light and pressure dipped beam.
One-chip computer programming control condition is as follows:
1. distance light dimming: when the distance light signal is effective; When the dipped beam signal is effective.
2. maintenance dipped beam: when the dipped beam signal is effective; When high light, dipped beam, distance light signal are effective simultaneously.
3. dipped beam becomes distance light: when high light is effective, and distance light, when dipped beam is all invalid.
4. flash of light once: before the distance light dimming.
5. glisten three times: when the pole changer signal is effective.
6. pressure distance light: when manually the distance light on-off signal is effective.
7. pressure dipped beam: when manually the dimmer control signal is effective.
The principle of work explanation:
During the automobile night travel, in two cars travel certain distance, utilize the country beam of the other side's lamp to shine mutually, photistor induction by light receiving unit, the hurried decline of QG1 junction resistance, make the Q1 conducting, electric current is extremely held through QG1, Q1, R4, RW1, on RW1 and R4, produce loss in voltage, the 1 foot current potential of U1 is raise, reach the logical one voltage thresholding of cmos circuit, make pin 2 output logics " 0 " voltage thresholding, this signal is delivered to control unit one-chip computer P1 mouth by signal cable (7).In like manner, under the light photograph of dipped beam, strong dipped beam, QG2 and QG3 distinguish conducting, and make 6 pin and the 10 pin output low level signals of U1, also are sent to the P1 mouth of one-chip computer.Owing to receive in the light box beam split baffle plate is arranged, make QG1, QG2, QG3 can be respectively to car bulb far away, near, high light is responsive.
The P1 mouth I0 mode of the one-chip computer 8751 of control unit (II) is by software set, and P10, P11, P12, P13, P14, P15 are changed to input mode, and P17 is changed to the way of output.The state of the P10～P15 of one-chip computer by reading in the P1 mouth is " 1 " or " 0 ", analyzing and judge, still is " 0 " with decision P17 pin output " 1 ", by the driving of photoelectric coupling circuit U4, relay is discharged or adhesive, and causing automobile headlamp is that country beam is bright or passing light is bright.Concrete software flow pattern as shown in Figure 5.
According to Fig. 5, the utility model both can make automobile that following function is arranged:
When the automobile night travel, two cars travel in 150 meters～200 meters of the relative distances, utilize the illumination of the country beam of the other side's car mutually, the induction of the photistor by light receiving unit, by 3 seconds kinds of light control unit time-delay, the headlight glare of controlling car separately once, and by the distance light dimming, afterwards, utilize the other side's passing light photograph mutually, keep square and travel, when two cars travel at a distance of 3 meters left and right sides with passing light, the high light of passing light is responded to mutually by both party, makes two headlights recover distance light by dipped beam.When with fleet's meeting, under the identification control of control unit, car keeps dipped beam always, finishes until last car meeting, recovers distance light.When overtaking other vehicles, spin, after controller is received the steering indicating light signal, control square lamp headlight glare three times, will overtake other vehicles to inform front truck to light switch.In particular cases, when (as the T-shaped road junction or the obstacle turning of being in the light is arranged) appears suddenly in the other side's car, this controller also immediately the Control of Automobile headlight recover distance light behind the meeting by the distance light dimming.
Characteristics of the present utility model are: simple in structure, advanced technology, intelligent automatic change light, the automatic flash of overtaking other vehicles does not affect former manual change light function, and hand control and automation becomes light and also deposits, manual priority, can handle complex situations (as with fleet meeting, unexpected meeting etc.), sensitive reliable, do not need the driver to intervene.
